NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 579,547, dated March 23, 1897; Application filed November 25, 1896. Serial No. 613,440. (No model.)

To all whom t may concern,.-

Be it known that I, GEORGE WV. PERRY, a citizen of the United States, residing at Voodside, in the county of Queens and State of New York, have invented certain new and useful Improvements in Automatic Axle-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

A This invention has reference to a novel construction in a nut-lock, and is adapted more especially for use for locking the nuts upon vehicle-axles.

The invention consists in the features of construction hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical longitudinal section of the end portion of an axle and its nut with this improvement appliedA thereto. Fig. 2 is a transverse section of the same, taken through the catch. Fig. 3 is an end elevation without the finger piece. Fig. 4 is a perspective view of the capl nut. Fig. 5 is a sectional view of the axle-nut.

It is understood, of course, that although this invention is shown and will be described with especial reference to an axle and its nut it is applicable for use in various other connections where it is desired to lock a nut upon a screw-threaded bolt.

Referring now to said drawings, 1 indicates the axle, bolt, or male member, and 2 the nut or female member. Within the member 1 is a longitudinal opening 3, extending inwardly from the end thereof, while a lateral opening 4 extends from a point near the inner end of said opening 3 through the side of the member 1. This lateral opening 4 is enlarged at its inner end, as shown at 5, for the purpose to be hereinafter referred to. The said opening 3 has a countersunk outer end portion 7. Situated within the opening 3 is a key-pin 8, having at its outer end a finger-piece 9 and at its inner end a catchpin l0. The said key-pin S is a little smaller than the opening 3 and is held therein by means of a collar 1l,

rigidly fastened to the inner end thereof and fitting nicely within the opening, and by means of a cap-nut 12, that screws into the 4conntersunk opening 7 of the member l and through which the keypin extends. The inner end of the key-pin does not reach the lateral opening 4, but the catch-pin 10 extends across the same. A catch 13 is situated within the lateral opening 4 and is pivoted at its inner end upon the catch-pin 10. It is seen from the foregoing description that the said catch 13 can be moved outwardly and inwardly by reason of the rotation of the keypin 8. The outer end of said catch stands normally a little beyond the outer face of the member 1, and to hold the catch in this position a spring 14 is employed that is connected at one end to the key-pin and at its other end to the cap-nut 12. This spring 14 has a tendency both to turn the key-pin and to draw it toward the inner end of the opening 3. To limit the rotation and the longitudinal movement of the key-pin, a finger 15 is employed, extending laterally from the key--pin at a point near its outer end adjacent to the finger-pieceQ, and which engages notches or projections 1G and 17 in a boss or projection 1S of the cap-n ut. The said notch or projection 16 is provided with an abrupt shoulder situated in the path of the linger l5, and the parts are so arranged that when the spring throws the finger l5 against this projection the outer end of the catch stands a little distance beyond the outer face of the member 1. This notch has also an inclined face to .allow a slight play of the finger l5, hereinafter referred to. It is thus seen that the finger 15 serves to hold the catch in the correct position, and it is obvious that it also limits the longitudinal movement of the key-pin.

-The notch 17 is situated in the path of the finger 15 and in such a position that when the key-pin is turned sufficiently to move the linger into this notch 17 the outer end of the catch is drawn sufliciently into the opening to allow the nut to turn freely upon the niember 1. The female member 2 or the axle-nut is constructed in the ordinary manner with the exception that it is provided with a plurality of interior longitudinal grooves 19 in the manner shown. It is preferable to allow these grooves 19 to extend only partially the length of the nut from the inner end thereof.

The parts being constructed and arranged as above described, it is obvious `that the nut IOO is screwed upon the bolt by retracting the catch sufficiently to allow the inner end oi the nut to pass thereover. Said catch can then be released, while the nut can be screwed onto the axle in the usual manner. When thus screwing the nut in place, the catch will move back and forth as the grooves 19 in the nut pass by the same, it being understood that when the grooves come opposite the end of the catch the spring will move the catch outwardly, and that when the nut is screwed into place the catch will stand within one of the grooves and effeotually prevent the unscrewing of the nut. As seen in Fig. 2, the catch stands at an incline or slightly tangential to the key-pin. This allows the catch to be easily moved backwardly by the nut. It is understood, of course, that the contact between the linger 15 and projection 16 holds the catch in this position, and, furthermore, that the enlarged inner end of the lateral opening 4 allows the rotation of the key-pin and catch and the side movement of the inner end of the catch. It will be noted that as the nut is screwed in place the finger 15 moves away from the projection 16 along the inclined face. The notch 17, however, is a little distance beyond the extent of the movement of this finger 15, and when the nut is to be unscrewed the key-pin is turned sufficiently to bring the nger 15 into the notch 17, into which it is held by the spring 14, and in this way the catch is held sufficiently retracted to allow the nut to be unscrewed without interference.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a nut-lock, the combination with a male member having a spring-actuated catch normally standing beyond the face of the same and means forretracting said spring-actuated catch and bringing its outer point within the face of said male member, of a female member provided with interior grooves to receive the end of said catch.
